SPECIFICATION forming part of Letters Patent No. 306,412, dated Getober 1%, 188%.

Application filed June 17, 1884.

T at whom it may concern.-

Be it known that 1, JAMES MALLoN, a citizen of the United States, residing at Hough ton, in the county of I-Ioughton and State of 5 Michigan, haveinvented a new and useful Improvement on Sleigh-Knees, of which the following is a specification, reference being bad to'the accompanying drawings.

This invention has relation to sleigh-knees; to and it has for its object to producea sleighknee that shall possess superior advantages over others of its class in point of cheapness, simplicity, durability, and general efficiency; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

Figure l is a side elevation ofa slciglrknee embodying my improvements. Fig. 2 is a plan view of the same. Fig. 8 is a vertical transverse sect-ion on the line w :r, Fig. 2.

Fig. 4. is a vertical longitudinal section of a,

modification.

Referring by letter to the accompanying 5 drawings, A designates the stanchion of the sleiglrknee, which is cast in one piece, comprising the flanges B along the under face of the top portion, the bolt-holes G G, the areshaped flanges D D 011 its upper face, at the 0 sides, on its middle portion, and the ball seat E at its middle portion, between the are flanges D l). The cap-plate F has a longitudinal rectangular groove, G, in its under face wide enough to receive the top of the stanchion A. The cap-plate F is provided near each end with a bolt-hole, H, having a rectangular countersink.

I designates a metal ball, which occupies the ball-seat E in the stanchion and the ball-seat 0 E in the cap-plate F.

J Jdesignate bolts with rectaiigularheads, which rest in the countersinks in the capplate F. These bolts J J pass down through the bolt-holes H in the cap-plate F and the 4,5 bolt-holes G O in the stanchion, and are provided below the flanges B with rubber wash- ,ers K one-half inch thick and metal washers L one-eighth inch thick, and are held in place by nuts M, as shown. The arc-flanges D D act as rockers for the cap-plate and stanchion, and prevent lateral motion or oscillation of the The cap-plate F is let into the beam part-s.

(No model.)

of the sleigh by means of two small returnflanges, and is bolted firmly to the beam at the right and left sides.

Instead of the rubber washers K, spiral springs may be used.

The object in using the ball (which has ample play in its seat) and the arc-flanges to produce the rocking motion of the cap-plate upon the stanchion isv to prevent the present wear and tear on the sleigh by giving it the rocking motion on the knees. The stanchions are bolted to the runners. This kneeis inexpensive, safer, and easier on the sleigh than any now in use, especially in traveling over rough and uneven roads, owing to the rocking lllO- tion before mentioned.

In heavy sleighs I use a belt or setscrew.

N, (see modification, Fig. i,) which is passed down through the cap-plate, ball, and into the circular hollow iron stanchion 0, having the rectangular top or shoulder to permit the wrought-iron brace I to slip over it, which bracecf itselfhas a tendency to act as a spring, and at the same time prevent the stanchion from shifting laterally. In this instance the ball is allowed ample play in its seat, and the brace is bolted to the runner. By this con struction I attain the rocking motion, the same So as in the construction first described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A sleigh-knee provided with a ball and arc-flanges between the cap-plate and stanchion, and mechanism, substantially as de scribed, for connecting the cap-plate and stanchion, to permit a rocking motion between the cap-plate and stanchion, as set forth. O

2. The combination, with the stanchion pro vided with the arc-flanges, ball-seat, and boltholes near its ends on the top part, of the capplate having the longitudinal groove, ball-seat, and countersunk bolt-holes, the bolts, rubber washers, metal washers, and securing-nuts, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in presence of two witnesses.

JAMES MALLON.
